Important Reminder:
The following is intended only to provide general information and not as a definitive basis for diagnosis or treatment in any particular case. It is very important that you consult with the doctor(s) about your specific condition.

Information About Our Procedures:


  • Pill Cam SB- (Small Bowel Capsule Endoscopy)
    Pill Cam SB is the most widely used, patient-friendly tool for directly visualizing the small bowel. Pill Cam SB is a vitamin-sized capsule that once ingested travels through the small bowel taking video images that help the physician detect the source of obscure bleeding, iron deficiency anemia and Crohn’s disease. This test is performed in the physician’s office.
  • SmartPill
    SmartPill is an ingestible capsule that measures pressure, pH and temperature as it travels though the gastrointestinal (GI) tract to assess GI motility. The SmartPill motility monitoring test is performed at the physician’s office to evaluate motility disorders like gastroparesis (a condition in which the contents of the stomach empty too slowly) and chronic constipation.
  • Radiofrequency Ablation Halo for Barrett’s Esophagus (HALO)
    If a patient is diagnosed with Barrett’s Esophagus and the biopsies contain areas of dysplasia, Radiofrequency Ablation therapy is performed to treat this issue. Ablation is a technique where tissue is heated until it is no longer viable or alive; The HALO ablation technology is a very specific type of ablation, in which heat energy is delivered in a precise and highly-controlled manner. HALO ablation therapy is performed in conjunction with an upper endoscopy (EGD). The treatment is performed in an outpatient setting and no incisions are involved.
  • Breath Test (UBT)
    The BreathID® Test is an easy, 10 minute test. You breathe normally after you are connected to a nasal breathing cannula. The BreathID® System automatically samples your breath, before and after you are given a 5 ounce solution to drink. Testing time is around 10 minutes, and the results are immediate.
    Your symptoms may be caused by a common bacterial infection called Helicobacter pylori (H.pylori). H.pylori affects nearly 1 in 3 Americans. It can cause common symptoms like heartburn, nausea, and bloating. It also is what causes up to 90% of stomach ulcers. If left untreated, it can sometimes lead to painful stomach inflammation, severe ulcers and, in some cases, can increase the risk of gastric cancer.
  • Ultrasound
    An ultrasound exam is a diagnostic technique used to evaluate internal body structures. Grey scale images are produced by high frequency sound waves which differentiate the shapes if various tissues and organs in the body. These images are generally referred to as a two dimensional (2D) image and/or B scan. We employ a certified licensed sonographer to perform these tests in our office.

  • Bravo™ Reflux Testing System
    A Simple way to evaluate your gastroesophageal symptoms.

    After administering a local anesthesia, your physician will place a Bravo™ reflux capsule into your esophagus using a delivery device. The test involves a miniature pH capsule, approximately the size of a gel cap, which is temporarily attached to the wall of your esophagus. Throughout the test period, the Bravo™ reflux capsule will measure the PH in your esophagus and transmit this information to the Bravo™ reflux recorder, worn on your belt or waistband just like a mobile phone. Once the Bravo™ reflux capsule has been placed and you have been instructed how to use the Bravo™ reflux recorder, you can leave the facility and go about your normal activities. Once the test has been completed, you will need to return the recorder according to your physician's offices instructions so that your test data can be downloaded for analysis. The information will be analyzed by your physician to diagnose your condition.
